Abstract
The invention relates to double layer high strength insulating pipe. It is made up of outer and inner tubes. The outer wall of the inner tube is set reinforcing bar of which another end is connected with the inner wall support of the outer tube. It has the advantages of material, time and labor savings, high strength, good insulating effect, economic, and durable.
Description
Technical field
The invention belongs to a kind of thermal insulation pipe, particularly a kind of double-layer high-strength heat-insulation pipe.
Background technique
The Winter protection of exposed pipeline outside in the market is the thick thermal insulating material of skin parcel that adopts at pipeline mostly; especially in the rural area; winter, the insulation of water supply pipe, drainage pipeline etc. all was thermal insulating materials such as the thick rope made of hemp, cotton in the outer wrap of pipeline; its heat insulation effect is poor; Shi Changhui generator tube road is by the phenomenon of bursting by freezing, and it is not only time-consuming, and waste material; both uneconomical, also impracticable.
Summary of the invention
The purpose of this invention is to provide a kind of double-layer high-strength heat-insulation pipe, it has overcome above-mentioned defective, has both saved material, has also saved man-hour simultaneously, has also increased intensity, has economical and practical effect.
Technological scheme of the present invention is: a kind of double-layer high-strength heat-insulation pipe is characterized in that: it is by outer tube and place the interior pipe of its inside to form, and the outer wall of said interior pipe is evenly equipped with stiffening rib, the inwall support and connection of the other end of this stiffening rib and outer tube.
Said stiffening rib is that fixed support is connected or movable supporting connects with outer tube wall.
The present invention has the following advantages: 1, save material, saving of work and time; 2, has high strength, high insulating effect, and economy and durability.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
As shown in the figure, a kind of double-layer high-strength heat-insulation pipe, it is by outer tube 1 and place the interior pipe 2 of its one to form, and the outer wall of said interior pipe 2 is evenly equipped with stiffening rib 3, and the other end of this stiffening rib 3 is connected with the inwall of outer tube 1; Said stiffening rib 3 is a single injection-molded with outer tube 1 inwall, and support and connection that are fixed as one or movable supporting connect.
Claims (2)
1, a kind of double-layer high-strength heat-insulation pipe is characterized in that: it is by outer tube and place the interior pipe of its inside to form, and the outer wall of said interior pipe is evenly equipped with stiffening rib, the inwall support and connection of the other end of this stiffening rib and outer tube.
2, a kind of double-layer high-strength heat-insulation pipe according to claim 1 is characterized in that: said stiffening rib is that fixed support is connected or movable supporting connects with outer tube wall.
